4 Claims. (Cl. 242-124) This invention relates to improvements in warpbeam or like constructions such as are used in the textile arts, andrelates more particularly to improved means for obtaining a secureconnection between the disc-like head and the cylinder or barrel.

Reference is made to the divisional and continuation-in-part applicationof Samuel A. Harris and Charles A. Sinqueeld Serial Number 339,594, ledMarch 2, 1953.

It has been a problem in this art to mount the head securely withrespect to the barrel so that the head will withstand the pressurescaused by the material wound on the barrel and th A principal object ofthis invention is to provide a novel joint between the barrel and thehead which will withstand the forces to which it is subjected. Severalrepresentative embodiments of the invention are illustrated anddescribed in the annexed drawings and following specification.

The invention is characterized generally by a novel connection including`an expansible annular member or device, such'as a collar or split ring,which is inserted into the bore of the barrel adjacent an end thereof,and expanded into contact therewith, means being provided to effect alockingconnection of the annular member to the barrel. The expansiblecollar, member, or device forms part of a new and improved arrangementfor connecting the head to the barrel. In certain forms of theinvention, a hub is locked to the barrel, and the beam headis secured tothe hub. v

In the drawings:

Figure 1 is a central, vertical, sectional view of a constructionembodying the invention; y

Figure 2 is a central, vertical, sectional view of a modifiedconstructiom' Figure 3 is a central, vertical, sectional view of afurther modified construction;

Figure 4 is a central, vertical, sectional view of still a furthermodified construction; and Figure 5 is a reduced front elevation of formshown in Figure 4.

The warp beam construction illustrated inA Figure 1 comprises a barrelInc and a head generally designated ||0 at one end of the barrel. Theopposite end of the barrel may be equipped with a similar head (notshown). The contacting faces of `the barrel luc and the periphery of acollar |30 within the barrel bore are provided respectively withregistering annular grooves or recesses |2c, |20', adapted to receive anexpansi- .the I ble ring 23. 'Ihe circular member or collar |30 isprovided with radially disposed threaded sockets one of which is shownat 24 connectingv theV inner bore of the collar with the bottom of therecess |20. Set screws, one of which is shown at 25, threaded in thesockets 24 may be brought to bear against the'inner wall of the ring 23to expand it so that its outer portion enters the recess |20 formed inthe barrel |0c. The head ||c, of plywood, is supported by a metal hubcomprising inner and outer face plates 26 and 21, respectively, theinner face plate 26 having a anged rim 26 Awhich is frictionally seatedwithin the bore of the collar |30. The head llc has a centrally disposedrecess ||c formed on its outer face, and the outer face plate 21 hasacorrespondingly shaped centrally disposed offset 21 which is seated inthe recess |10. The two face plates 26 and 21 are securely connectedtogether, with the head ||0 between them, by means of bolts, rivets, orother suitable fastening vmeans 28. The inner face plate 26, the head||c, and the outer face plate 21 are provided With a common centralbore, generally designated 29, into which the hub 20a of a gudgeon orstub shaft is inserted, the flanged portion 2|an of the hub 20an beingseated in a recess |901.I formed in the outer face plate 21 within theoiset 21.

The beam head, forming a complete unit including the face plates 26 and21, is secured as a unit to the collar |30 by bolts I1c passing throughthe face plate 21, head llc, and intov the threaded sockets in thecollar |30.

In assembling the construction shown in Figure 1, the collar |30, withthe ring 23 seated in the recess |20', will first be inserted in thebore of the barrel |00, and the outer edge of the collar will be alignedwith the edge of the barrel. As the recesses |20, |20 are located equaldistances from the outer edges of the barrel Ic and the collar |30respectively, the recesses will then register with each other. The setscrews 25 may then be turned so as to expand the split ring 23, forcingit partially into the barrel recess |20, the remaining ring portionremaining in the collar recess |20. The ring 23 thus acts as a keybetween the barrel |00 and collar |30, eectively locking them together.The rim 26' of the face plate 26, with its attached parts, may then beseated in the bore of collar |30, and the entire head unit secured tothe collar by means of bolts |10.

A modification is disclosed in Figure 2. In

-this construction, a circular flanged or rimmed face plate member 26dis seated directly within the bore of the barrel 10d instead of within aseparate collar as in Figure 1. The outer face 26d of the face plate isspaced slightly inwardly from the end of the barrel, leaving the barrelend projecting slightly for a purpose which will be describedv later.

The meetingifacespfthe bore of the barrel 10d and the collar part or rimI3d of the face plate 26d are provided respectively with oppositelydis,-J posed annular recesses or grooves lzirand( 172g". An expansiblesplit ring 23d is seat'ed the recess |211 of the rim @gli Theu ldisprovided with radially spacegithreadedsoelgets` 24d, and set screws 25darehfeadedlin eaclL 15 denwy, andstheadjacent barrel end, axially of ofthese sockets.

When the collar is pushedinwardly into the bore of the barrel Ille, the ring 23e will be exposedand freed so that it may be removed, after which the collar may bewithdrawn from the endvoithe barrel;
